The Nocturne covers the old long wave marine band but nothing is likely to be found there anymore. Then it continuously covers from 550 KHz to over 19MHz in 4 overlapping bands. An interesting feature is the Band Expander knob, second from the left. It turns a cam which moves the core of the Oscillator and I.F. coils. It's intent apparently was to allow the user more precise tuning to bring in weak signals.
